Abstract: 1278734 Evaporators, wiped-film type; reactor LUWA AG 20 March 1970 [21 March 1969] 13539/70 Headings BIB and BIX A viscous liquid, supplied through inlet 14, is mixed on the inner surface of a chamber 12 by means of a rotor 42 to which are secured two rows of vane stubs 44 inclined to the axis of rotation of the rotor and having gaps therebetween, the rotor also carrying two axiallyextending wiper blades 46 which are radially offset at less than 90 with respect to a row of vane stubs. The wiper blades follow the vane stubbs during the rotation of the rotor. The blades 46 repeatedly spread the liquid as a thin film, while the stubs 44 displace it in the form of drops towards the outlet 16. In the case of an evaporator, heating-medium is passed through jackets 20 and 26; and vapours ascend through rotating blades 48 and are withdrawn through outlet 34. The treated liquid flows through grooves 52 in rim member 50 and is discharged through outlet 16 by means of rotary worm 60. In modified constructions (Figs. 3 and 4, not shown) the outlet margin of each wiper blade is bent in a direction opposite to the direction of rotation of the rotor. The apparatus may be used as a reactor, the reactants being mixed prior to introduction into chamber 12. When carrying out exothermic reactions, jacket 20 may be used for cooling.

Abstract: 1308982 Remotely controlled vehicles CATERPILLAR TRACTOR CO 24 March 1970 [7 May 1969] 14184/70 Heading B7H [Also in Division E1] A powered vehicle may be controlled by a driver in situ, through control linkages, or remotely by a plurality of fluid-operated jacks forming part of the linkages controlled by signals, e.g. radio signals emanating from a control system when the parts of the linkages actuated by the driver are immobolized. As shown, an endless track loader has a body 12 carried by endless tracks 13, a bucket 16 carried by lift arms 17 actuated by lift jacks 22 and tilt jacks 24. Motion of the loader is controlled by the driver through a throttle lever 28, transmission lever 30, steering pedals 27, 61, and 62 and a start stop switch 26. Lift and tilt levers 29 and 31 control actuation of the bucket 16. When the loader is to be remotely controlled, the levers 29 and 31 are immobolized by a bolt 48 passed through a housing 39. An hydraulic jack 37, Fig. 2, acts as a rigid link when the lever 29 is operated by the driver, but upon immobolization extension and retraction of the jack actuates a valve 36 in one of several positions for controlling jacks 22. Jacks (24), Fig. 4 (not shown), are similarly controlled. A clutch (69) and brakes (72), Fig. 5 (not shown), are controlled by the driver through pedals (61), (62) and (27) or remotely by jacks 87. The various jacks for effecting remote control of vehicle motion, steering, and actuation of the bucket 16, Fig. 1, are controlled by solenoid control valve, e.g. (132, 133, 134), Fig. 10 (not shown), for the jack 37, Fig. 2, such that by appropriate sequencing raise, hold, lower and float of the bucket is achieved. The solenoid valves are controlled by switches (162), Fig. 11 (not shown), which each define an individual setting of the jacks. The switches may be controlled from a remote control by a multi-conductor cable or as shown by radio signals from a control bore (202) connected to an encoder (206) feeding a transmitter (208) supplying a receiver (209) on the loader.

Abstract: 1,097,857. Automatic exchange systems. SIEMENS A.G. March 31, 1966 [April 1, 1965], No. 14201/66. Heading H4K. In an exchange system, a calling subscriber is initially connected through a switching network to a register which in dependence on the digits dialled is then connected, also via the network, to a relevant relay set (link circuit) whereafter a direct connection through the network between the caller and the relay set is set up, the " by-pass " connection via the register being released. The switches used in the network are not specified but the network may be a full access one having subscriber circuits and relay sets connected on the same or opposite sides thereof. The system may be a main exchange or a PBX. Outgoing call.-In response to looping of a subscriber's (T1) line, his line circuit TS1 transmits a start signal to a common marker MK which thereupon connects the circuit via the network KF to the inlet E of a free register. When sufficient digits have been received the register is connected over switch RAK to the marker, whereby a path from the outlet A of the register to a relevant relay set, e.g. outgoing set VU1 is set up. The register includes translation and sending facilities and proceeds to send its stored data over the outgoing trunk VL1. When the called party replies, the register is again connected to the marker which then selects and sets up a direct path from the calling line circuit TS 1 to the outgoing relay set VU1 and releases the paths to and from the register. Alternatively, the marker may store a preselected direct path which is immediately set up when the called party replies. Local call.-This proceeds as before except that the marker connects the register to a local relay set JVS. The latter is effectively short-circuited until the called party replies, supervision and feeding being performed by the register until this time.
